The meanings of "science" and "technology" have changed significantly from one generation to another. More similarities than differences, however, can be found between the terms. 46) {{U}}Both science and technology imply a thinking process, both are concerned with causal relationships in the material world and both employ an experimental methodology that results in empirical demonstrations that can be verified by repetition.{{/U}} 47) {{U}}Science, at least in theory, is less concerned with the practicality of its results and more concerned with the development of general laws, but in practice science and technology are inextricably involved with each other.{{/U}} The varying interplay of the two can be observed in the historical development of such practitioners as chemists, engineers, physicists, astronomers, carpenters, potters, and many other specialists. Differing educational requirements, social status, vocabulary, methodology, and types of rewards, as well as institutional objectives and professional goals, contribute to such distinctions as can be made between the activities of scientists and technologists; but throughout history the practitioners of "pure" science have made many practical as well as theoretical contributions. 48) {{U}}Indeed, the concept that science provides the ideas for technological innovations and that pure research is therefore essential for any significant advancement in industrial civilization is essentially a myth.{{/U}} Most of the greatest changes in industrial civilization cannot be traced to the laboratory. Fundamental tools and processes in the fields of mechanics, chemistry, astronomy, metallurgy, and hydraulics were developed before the laws governing their functions were discovered. The steam engine, for example, was commonplace before the science of thermodynamics elucidated the physical principle underlying its operations. In recent years a sharp value distinction has grown up between science and technology. Advances in science have frequently had their bitter opponents, but today many people have come to fear technology much more than science. 49) {{U}}For these people, science may be perceived as a serene, objective source for understanding the eternal laws of nature, whereas the practical manifestations of technology in the modern world now seem to them to be out of control.{{/U}} 50) {{U}}Many historians of science argue not only that technology is an essential condition of advanced, industrial civilization but also that the rate of technological change has developed its own momentum in recent centuries.{{/U}} Innovations now seem to appear at a rate that increase geometrically, without respect to geographical limits or political systems. These innovations tend to transform traditional cultural systems, frequently with unexpected social consequences. Thus technology can be conceived as both a creative and a destructive process.

问答题In future, as newspaper fade and change, will politicians therefore burgle their opponents" offices without punishment? Journalism schools and think-tanks, especially in America, are worried about the effect of a collapsing journalism. Nobody should enjoy the disappearance of once-great newspapers. But the decline of newspapers will not be as harmful to society as some fear. 46. Denmocracy, remember, has already survived the huge television-led decline in circulation since the 1950s. It has survived as readers have evaded papers and papers have evaded what was in conservative times thought of as serious news . And it will surely survive the decline to come. 47. A few papers that invest in investigative stories which often benefit society the inost are in a good position to survive, as long as their owners do a comnpetent job of adjusting to changing circumstances. Publications like the New York Times and the Wall Street Journal should be able to put up the price of their journalism to compensate for advertising revenues lost to the internet—especially as they cater to a more global readership. 48. As with many industries, it is those in the middle—neither highbrow, nor entertainingly populist—that are likeliest to fall by the wayside. 49. The usefulness of the press goes much wider than investigating abuses or even spreading general news; it lies in holding governments to account--trying them in the court of public opinion. The internet has expanded this court. Anyone looking for information has never been better equipped. People no longer have to trust a handful of national papers or, worse, their local city paper. News-aggre-gation sites such as Google News draw together sources from around the world. The website of Britain"s Guardian now has nearly half as many readers in America as it does at home. 50. Furthermore, a new force of "citizen" journalists is itc.hing to hold politicians to account. The web has opened the closed world of professional editors and reporters to anyone with a keyboard and an internet connection. Several companies have been chastened by amateur postings—of flames erupting from Dell"s laptops or of cable TV repairmen asleep on the sofa. Each blogger is capable of bias and slander, but, taken as a group, bloggers offer the searcher after truth boundless material to chew over. Of course, the internet panders to closed minds; but so has much of the press.

问答题In the last two years of the 1840's San Francisco exploded onto the world map; a small village on America' s West Coast rose in a few months to become a "boom" town for gambling, drinking and violence. (1) From the four comers of the earth, from Europe, China, India and Australia, men met on the west coast with one aim — Gold, which was the magnet that attacted these first settlers. It had all started on the 24th January 1848, when a workman came across gold in a river in the Sacramento valley. (2) Almost overnight, this discovery was known up and down the Pacific coast, and the news of quick fortunes to be made spread rapidly eastwards with amazing effects. Men who had previously been thought sensible and industrious left their jobs, wives, families and homes and set out to join the rush to California. All possible routes were taken by the forty-niners(1848年去加州淘金的人) as these pioneers came to be called, who set out to find gold; they sailed round Cape Horn, they crossed at the Isthmus of Panama, or they tripped across the continent along the Oregon or California Trails. (3) And with the honest fortune-seekers came men who were lees, particular as to how they made their money. It was inevitably the more reckless and adventurous, and those who had least to lose, who were among the first to jump onto the bandwagon and who came off best. The common desire to get rich quickly mused the violence and terrorism that swept the California gold-fields. (4) Men who had given up everything became desperate in their search for wealth; they would rob their friends of gold, make their fortunes only to lose them, and possibly their lives, in the gambling house of San Francisco. And of course, hot on the heels of the gold explorers came others, more practiced in the art of money-making, like businessmen, lawyers and saloon-own ers, to serve the newly-rich settlers. Speculation in land was an easier and safer way to get rich than separating gold from dirt in the gold-fields; and so was the job of providing whisky, women and gambling facilities for the explorers, usually at absurdly high prices measured in pinches(微量) of gold. (5) The excitement was, however, short-lived; within a very few years the place of these first violent settlers had been taken by farmer% shop-owners and professional men, who under took in a more reasonable fashion the formation of the new state of' California.
